Acute cardiac care & resuscitation

Wearable-based automated cardiac arrest detection and alerting: A systematic review

ResuscitationPublished Systematic review

Authors' conclusion

Wearable devices have demonstrated promising sensitivity for detecting cardiac arrest. However, (external) validation and real-life data are scarce, and the sensitivity-false alarm trade-off requires further investigation.

Study context

Population
Studies describing non-invasive, intended wearable systems designed to detect out-of-hospital cardiac arrest (OHCA) and reporting on their detection performancepublications included, from 6,344 records screened, number of participants ranging from 18 to 1,423
Participants
13 participants
Outcome
Sensitivity for cardiac arrest detection
